Kevin,
Just set overwrite to "false" :
<project name="Proptest" default="testProperty">
<property name="ENV" value="DEV" overwrite="false" readonly="false" />
<target name="testProperty">
<echo message="${ENV}" />
</target>
</project>Hope this helps,
Gert

Assume a sample build file
<project name="Proptest" default="testProperty"> <property name="ENV" value="DEV" overwrite="true" readonly="false" /> <target name="testProperty"> <echo message="${ENV}" /> </target> </project>
When this is run the output is
C:\Temp\nantest>C:\nant\bin\NAnt.exe NAnt 0.85 (Build 0.85.1684.0; net-1.0.win32; nightly; 8/11/2004) Copyright (C) 2001-2004 Gerry Shaw http://nant.sourceforge.net
Buildfile: file:///C:/Temp/nantest/test.build Target(s) specified: testProperty
testProperty:
[echo] DEV
BUILD SUCCEEDED
Total time: 0.1 seconds.
However when I try to set ENV on the command line I lose - output follows
C:\Temp\nantest>C:\nant\bin\NAnt.exe -D:ENV=JOE NAnt 0.85 (Build 0.85.1684.0; net-1.0.win32; nightly; 8/11/2004) Copyright (C) 2001-2004 Gerry Shaw http://nant.sourceforge.net
Buildfile: file:///C:/Temp/nantest/test.build Target(s) specified: testProperty
BUILD FAILED
C:\Temp\nantest\test.build(2,3): Read-only property "ENV" cannot be overwritten.
Total time: 0 seconds.
Do I really need to go through the absurd little dance of setting up two
properties, one to accept command line input and one to set a default value
if the command line property has not been set? Or is my build bad? As you
can see I am using a fairly recent nightly build...
